(54)	Organic light emitting display device and method of fabricating the same

(57) An organic light emitting display device and a method of fabricating the same. A dummy pattern (328,336,356) is formed in an emission region (I) to increase the step height of the emission region (I) by an electrode material while a thin film transistor is fabricated, so that a distance between a pixel electrode and a donor film (T2) is decreased during fabrication of an organic layer. This reduced distance (T2) reduces laser energy for transfer using laser-induced thermal imaging, thus improving life span and efficiency of the device. Further, the pixel electrode (380) can extend into a thin film transistor region (II) and a capacitor region (III), thus enhancing an aperture ratio.
